I think Serena has the biggest chances to become #1 after AO.
Vika actually might fall from 1 to 3
Masha staying #2 forever
Aga has slim chances to break into Top 3 with a SF/RU and one of the other girls losing early

What will your reaction be when, inspite of your waffling about Azarenka being in a different league to Maria, Maria will almost certainly be ranked ahead of Vika in 2 weeks' time? (Serena only needs to make the semis I think and then Azarenka loses #1 no matter what.)

When what I'm saying is so wrong and pointless, why does it get your panties all in a bunch then?

Just because a player lost to someone while recovering from injury that means she is going to lose to that someone for sure the next time they meet? Oh they did play each other again after that and I bet you missed the match and the results, otherwise you didn't recycle your unfunny joke. It's okay at st, but recycling is getting tiresome.

Anyway, on paper Vika has the least chance to keep her No1 ranking since even if she beats Serena in the SF and Maria or any other players in the F. Serena then will be the No1. If Maria beats Vika in the F, then Maria will get to No1. Vika has a very soft draw this year, so repeat her title is not impossible, but her No1 ranking is definitely in trouble, unless some shocking results happens.
